A good clean, just like bergs, then its a soak in the nice hot chain lube. After heating it up and letting the hot chain drip the excess goo back into the tin, I write the date and miles in the solidified lubricant. Then instead of trying to remember last time I did it, just open up the tin. Camping stove outside is safer, but less steady. Indoors if thing go wrong you will in deep !!!! You are faced with walking the melted tin and chain outside, or removing the dripping chain. Both have DISASTER writ BIG.
